摘　　要：提出一个模拟土体-结构非线性相互作用的模型,用于整体式桥台桥梁的动力特性分析。在此基础上建立一座整体式桥台桥梁的有限元模型,分析了土体-结构非线性相互作用和整体式桥台桥梁动力特性之间的关系,并讨论了主要参数对整体式桥台桥梁动力特性的影响。研究结果有助于认识整体式桥台桥梁的动力性能。A model for simulating nonlinear soil-structure interaction of Integral Abutment Bridges is presented in dynamic analysis of this bridges. Based on this the finite element model of a integral abutment bridge is built and the vibration properties(mode shape、frequency.etc) of the structure are analyzed. Then the influence of soil reaction to the dynamic characteristic of structure is examined and the chief parameters that influence strongly it are found out﹒The results can help to unterstand the dynamic prope...
